Recently, Microsoft reported a new nation-state threat actor, code-named Peach Sandstorm linked to the Iranian government, specifically the Islamic Revolutionary Guard Corps (IRGC). This article delves into the tactics employed by Peach Sandstorm, particularly their use of Tickler malware and password spray attacks, while offering insights on Microsoft 365 Security measures to protect your organization. So, it’s important to be aware of such viruses as Peach Sandstorm and know how to protect your company against them.
Understanding The Peach Sandstorm Virus: Why it Can Harm You
Peach Sandstorm has been actively targeting sectors including satellite communications, oil and gas, and federal and state governments in the United States and the United Arab Emirates. Their operations signify a shift toward persistent intelligence-gathering objectives and represent a new evolution in their long-standing cyber campaigns.
Common Attack Reasons
One of the primary techniques employed by Peach Sandstorm is password spray attacks. These attacks, although familiar, continue to be effective due to several factors:
- Lack of Multi-Factor Authentication (MFA): Many organizations have not enforced MFA across all accounts, making them susceptible.
- Weak Passwords: The reuse of passwords or the selection of weak passwords remains prevalent, allowing attackers to exploit vulnerabilities.
Through these strategies, Peach Sandstorm successfully compromised accounts, particularly in educational institutions, to gain access to Azure educational tenants for further attacks.
Strengthening Your Defense: Advanced Microsoft 365 Security Solutions
1. Combatting Password Spray Attacks
To effectively defend against password spray attacks, consider implementing the following measures:
- Forced Password Resets: Reset passwords for any accounts exhibiting unusual login attempts. Utilize Azure sign-in logs to monitor suspicious activity.
- Session Cookie Revocation: Revoke session cookies for accounts whose passwords you reset to enhance security.
2. Enhancing Account Security
Microsoft recommends improving account security by leveraging tools such as Entra password protection and Entra identity protection. These tools help mitigate the risk of poor password selection and enhance risk detection.
3. User Training and Awareness
Training users to regularly review their sign-in activity can significantly bolster your organization’s defenses. Encourage users to flag any unauthorized activity in their “My sign-ins” portal.
4. Risk-Based Policies
Consider employing risk-based conditional access policies that require additional security measures in response to risky sign-ins detected by Entra. Although these may require premium licenses, the enhanced security justifies the investment.
Mitigating the Tickler Malware Threat
To defend against the Tickler malware, ensure you have an Endpoint Detection and Response (EDR) system in place that can automatically download signatures and block known malicious behavior. If you lack an EDR solution, prioritize its implementation as part of your cybersecurity strategy.
